VALVE OR FAUCET.

SPEGFICATION forming part of LettersfPatent No. 761,433, dated May 31,1904.

l Application filed December 6, 1902. Serial No. 134,122. (No model.)

ton and State of Ohio, have invented certain new and useful Improvementsin Valves or Faucets, of which the following is a specification.

This invention relates to certain improvements in valves or faucets,such as are adapted for controllIng the iiow of iiuids through passages;and the object of the invention is to lprovide a'device of thischaracter with auxill' iary means for controlling the flow of iiuidindependently of the control exercised through the medium of the mainvalve, so that the vescape of iuid past the main valve is preventedVwhen said main valve Is removed for repairs. The auxlliarycontrolhng'means also permitsv of regulating the pressure of theiuid in iowing pastthe main valve, so that damage due to sudden vchecking of the* flow atthe main valve is prevented.

The invention consistsvin certain novel features ofthe construction,combination, and ar rangement of the several parts of the improved lvalve or faucet whereby certain important vadvantages are attained andthe device is made simpler, cheaper, and otherwise better adapted andmore convenient for use, all as will be Y hereina'fter fully set forth.

The novel features of the inventionwill be carefully defined in theclaim.

In the accompanying drawings', which serve to illustrate my invention,Figure 1 isa side elevation of a valve or Yfaucetconstructed accordingto my invention, and Fig. 2 is an axial section taken through the valveor faucet and showing the main valve and auxiliary control-v ling meansthereof. Fig. B is a view similar to Fig. 2, but showing the main valvein opened position and the auxiliarycontrolling means adjusted inposition for reducing the fluidpressure within the casing of the valveor faucet; I

As shown in these views, the improved valve or faucet 'embodyingmyimprovements is provided with a casing or body portion 1, having atone side ascrew-threaded extension 2 projecting 'fromit and adapted forconnection witha service-pipe,(not shown,)said extension 2 being formedwith a bore or passage 3, through which the fluid is adapted to flowfrom said service-pipe into the hollow interior or chamberof the main orbody portion of the valve or faucet easing 1. A

4 indicates apartition extended transversely and horizontally across theinterior hollow or ychamber of the main or bodyportion of the casing 1,and said partition 4 serves to divide .said ychamber into a lowercompartment 5, with which the passage or bore 3 has free communicationfor the supply of fluid,'and an upper compartment 6 above saidpartition, communication between the lower and upper compartments and 6being afforded by way of a port 7, formed in said partition 4. At theside opposite'to the extensionl 2 the casing 1 of the valve or faucet isprovided with a discharge-nozzle 8 having a bore or passage 9,

Vadapted for communication with the upper `compartment 6 for thedischargeof fluid from the casing. f I v The partition 4isprovidedwitlrtwo valveseats, one of which is indicated at10 and isground to a conical form upon the lower or under side of said partitionand within the `lower compartment 5, being concentric around the port 7in the partition. The other valve.-

seat is indicated at 11 and is made in raised annular formwithintheupper compartment 6 and upon the upper surface of the partition and isalso concentric with respect to the port 7 in said partition.

The casing 1 of the valve or faucet is. provided at its upper part withan upwardly-extended boss or extension 12,1.the interior of which is incommunication with the upper `compartment 6 in the casing and theexternal wall of which is screw-threaded to receive a screw-cap 13,between which andv the upper edge of said boss vor extension 12 is helda gasket or packing-ring 14, of rubber or other suitable material. Thelower interiorly-screwthreaded portion of the cap 13 is made inhexagonal form, so as to be capable of ready removal by means of awrench or other tool, and said cap is provided with a reduced andinteriorly-screw-threaded neck 15 at its upper part, within`which isarranged to screw a valve-stem 16, havingscrew-threads for engagement insaid interior screw -threads of the neck 15, as .shownat 17,.and alsoprovided at its lower end ywith a head or enlargement 18, held upon it,which head or enlargement carries a flat valve 19, of rubber or othersuitable substance, adapted when the valve-stem 16 is turned to be movedtoward and away from the upper raised valve-seat 11, the stem '16 beingaxially alined above the port 11, so

that the valve 19 may fit snugly upon said seat l1 when the stem isscrewed down into the casing. The stem 16 is provided at its upper endwith a handle 20 of any preferred kind, and in order to prevent theescape or leakage of fluid around the stem in case the screw-threadsthereof should not properly correspond with those ot' the neck 15 Iprovide said neck 15 with exterior' screw-threads whereon is engaged anauxiliary cap 2l, adapted to hold a packing 22 to produce a tight jointaround the upper part of the valvestem 16.

The lower part of the casing 1 of the valve or faucet is also providedwith a downwardlyextended nipple or boss 24, which is exteriorlyscrewethreaded to receive a screw-cap 25, within which is held apacking-ring or gasket 26 for producing a tight joint at the lower edgeof said nipple or boss.v TheI nipple or boss 24 is also provided withinterior screw-threads, with which is engaged ascrewthreaded A part 27,produced upon a lower auxiliary-valve stem 28, the upper end ofl whichcarries a cone-shaped valve 29, adapted to fit the valve-seat 10 uponthe under side of partition 4 and within the lower compartment 5 of theeasing, the' lower end of said stem 28 being extended ,through thescrew-cap 25 and having a handle 30 of any desired kind below the same.

The lower or auxiliary valve 29 and its valve-stem 28 are arranged inaxial alinement with the upper or main valve 20 and its valvestem 16,and 'the construction is such that either of said valves may by turningmovement ot 1ts valve-stem be adjusted nearer to or farther from itsvalve-seat or may be pressed closely upon its valve-seat, so that eithervone of said valves may for controlling the liow of iiuid port 7. i

The valve-stem 28 of the lower or auxiliary valve 29 is formed at itsjunction with the enlarged screw-threaded part 27 with a graduallyenlarged or tapered portion 31, as shown in Figs. 2 and 3, and on thesaid. valve-stem 28 below said tapered portion is held an annularpacking-ring or annulus 32, which when the valve 29 is drawn downward byturning movement which causes the part 27 to traverse the screw-threadsin the nipple or boss 24 is clamped between said enlarged screw-threadedpart 27 and the packing 26 at the base of the screwcap 25, the expandedor tapered portion be employed through the 31 of the valve-stem being'at the same time pressed into close contact with the central opening insaid packing-ring 32 in such a way as to produce a tight joint andprevent leakage at the base of the casing. 1n this way it will be seenthat by drawing the auxiliary valve down tightly to compress the packingbelow it leakage at that point may be eli'ectually prevented, so thatrepairs of the auxiliary valve are not required.

In the use ot' the improved valve or laucet constructed according to myinvention the upper or main valve 20 is normally employed forcontrolling the flow of liuid through the passages from theservice-pipe, the lower or auxiliary valve 29 being left normally open;but when it is necessary to repair the upper or main valve, or in casesaid main valve should become so worn in use as to permit escape ot'lluid past it, the lower or auxiliary valve 29 is operated and b vengagement upon its seat 10 serves to effectually cut oli' the flow ofliquid through the passages. When the lower or auxiliary Valve 29 is inclosed position, the fiow of li uid through the valve or faucet beingcompletely cut oil' thereby, the removal olf' the main valve and itsstem by the unscrewing of the cap 13 is permitted, so that ready accessmay be had to all of the parts above the partition 4 for purposes ofrepair.

seldom used, it will be evident that there will be but little wear uponit, so that it will not require repairing except in case oil accident orafter long service. Said lower or auxiliary valve is also capable of usefor regulating the pressure with which the liquid may escape through theport 7 in partition 4, since it can be adjusted to stand more or lessclosely adjacent to its seat 10, as indicated in Fig. 3 of the drawings.In this way the strains exerted by the Huid upon being suddenly checkedat the main valve may be regulated, so that damage to the parts may beavoided. It will also be seen that when the auxiliary valve is screweddown tightly away from its seat it will act to clamp the packing heldupon its stem in such a way as to effectively prevent leakage at thispoint even after the parts shall have been considerably worn. In thisway repair otl the auxiliary valve is avoided and a material advantageis thereby attained, since to repair said auxiliary valve wouldnecessitate shutting oif the water-supply to the service-pipe with whichthe valve or faucet is connected.

The improved valve or faucet constructed according to my invention is ofan extremely simple and inexpensive construction and is very light,strong, and durable, and by its use permits a considerable economy,since it permits of dispensing with the extra cock or valve commonlyprovided in the service-pipe, and also obviates the use of extra joints,such as are required for connecting such extra cock IOO IIO

or valve in the service-pipe, lthe cost of such extra cock and joints,together with the labor involved in putting them in position, beinggreatly in excess of the increased cost of the valve or faucet providedwith my improvements. Moreover, the auxiliary Valve in my improvedconstruction is always ready and in convenient position for use, so thatthe anrily provided, and when so used the auxiliary valve may be turnedto closed position Vwhen it is desired to repair the main valve, so thatwasting of the watercontain'ed in'the boiler and loss of time andannoyance occasioned in refilling said boiler are` avoided.

From Vthe above description it will be seen that the invention is notlimited in its application to valves or faucets constructed withdischarge-nozzles, but may as well be used in connection with valves orcocks of other constructions, and for this reason I do no t wish to beunderstood as limiting myself to the employment of my improvements inconnection with discharge-faucets alone.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

A device of the type set forth comprising a casing having a partitiondividing the same into upper and lower compartments, said partitionbeing formed with a part surrounded on the upper and lower facesrespectively of the partition with valve-seats, an internallythreadednipple formed integral with the under side of the casing and being incommunication with the lower compartment and having an interior of lessdiameter than that of the said lower compartment, a valve operating inthe upper compartment and being adapted to engage the upper valve-seat,a stem projectingv through said nipple and having an enlarged portionthreaded and engaging the threaded interior of said nipple, a valve onthe inner end of said stem.l said valve being of less diameter than theenlarged portion of said stem, a cap on the lower end of said nipple, agasket arranged in said cap and engaging the lower end of the nipple,and a second gasket superimposed on said rst-named gasket and beingarranged in said nipple, said stem from its enlarged portion beinggradually reduced in diameter whereby an inclined portion which isarranged -in said last-named gasket is provided, said inclined portionof said stem being located at the upper face of the second-named gasket,so as'to compress the latter inte the opening of the first-named gasketwhen the Valve is in its lowermost position, said second-named gasket onits lower face adjacent the stem having a tapered portion snuglyembracing the stem, substantially as and for the purposespeciiied.
